Find the length of the wire required to fence a field of length 290m and width of 75.25m. |
|
Answer» Answer: The length of the wire required to fence the FIELD is 730.5 m Step-by-step EXPLANATION: Given : The length of the field = 290 m The width of the field = 75.25 m To FIND : the length of the wire required to fence the field Solution : We have to find the perimeter of the RECTANGLE which is the length of the wire required to fence the field. Length of the wire required = Perimeter of the rectangle ⇒ Length of the wire required = 2(length + breadth) ⇒ Length of the wire required = 2(290 + 79.25) ⇒ Length of the wire required = 2(365.25) ⇒ Length of the wire required = 730.5 m Therefore, the length of the wire required to fence the field is 730.5 m |

1. Find the areas of the following figures by counting square:(a)(b)(c)(d)(c)(1)(8)(h)(1)(k)(1)(m)(n) |
|
Answer» (a) Number of filled square = 9 \therefore∴ Area covered by squares = 9 x 1 = 9 sq. units (b) Number of filled squares = 5 \therefore∴ Area covered by filled squares = 5 x 1 = 5 sq. units (c) Number of FULL filled squares = 2 Number of half filled squares = 4 \therefore∴ Area covered by full filled squares = 2 x 1 = 2 sq. units And Area covered by half filled squares = x = 2 sq. units \therefore∴ Total area = 2 + 2 = 4 sq. units (d) Number of filled squares = 8 \therefore∴ Area covered by filled squares = 8 x 1 = 8 sq. units (e) Number of filled squares = 10 \therefore∴ Area covered by filled squares = 10 x 1 = 10 sq. units (f) Number of full filled squares = 2 Number of half filled squares = 4 \therefore∴ Area covered by full filled squares = 2 x 1 = 2 sq. units And Area covered by half filled squares = x = 2 sq. units \therefore∴ Total area = 2 + 2 = 4 sq. units (g) Number of full filled squares = 4 Number of half filled squares = 2 \therefore∴ Area covered by full filled squares = 4 x 1 = 4 sq. units And Area covered by half filled squares = x = 2 sq. units \therefore∴ Total area = 4 + 2 = 6 sq. units (h) Number of filled squares = 5 \therefore∴ Area covered by filled squares = 5 x 1 = 5 sq. units (i) Number of filled squares = 9 \therefore∴ Area covered by filled squares = 9 x 1 = 9 sq. units (j) Number of full filled squares = 2 Number of half filled squares = 4 \therefore∴ Area covered by full filled squares = 2 x 1 = 2 sq. units And Area covered by half filled squares = x = 2 sq. units \therefore∴ Total area = 2 + 2 = 4 sq. units (k) Number of full filled squares = 4 Number of half filled squares = 2 \therefore∴ Area covered by full filled squares = 4 x 1 = 4 sq. units And Area covered by half filled squares = x = 1 sq. units \therefore∴ Total area = 4 + 1 = 5 sq. units (l) Number of full filled squares = 3 Number of half filled squares = 10 \therefore∴ Area covered by full filled squares = 3 x 1 = 3 sq. units And Area covered by half filled squares = x = 5 sq. units \therefore∴ Total area = 3 + 5 = 8 sq. units (m) Number of full filled squares = 7 Number of half filled squares = 14 \therefore∴ Area covered by full filled squares = 7 x 1 = 7 sq. units And Area covered by half filled squares = x = 7 sq. units \therefore∴ Total area = 7 + 7 = 14 sq. units (n) Number of full filled squares = 10 Number of half filled squares = 16 \therefore∴ Area covered by full filled squares = 10 x 1 = 10 sq. units And Area covered by half filled squares = x = 8 sq. units \therefore∴ Total area = 10 + 8 = 18 sq. units .
