A field is in the shape of a trapezium whose-parallel sides are 25 m and 10 m. The non-parallel sides are 13 m and 14 m. Find the area of the field.

Answer»

Given: AB || CDAB =25 m CD= 10m BC=14mAD= 13m

From point C draw CE || DA . Hence ADCE is a ||grm having CD || AE & AD||CE

AE= CD= 10mCE= AD= 13mBE= AB- AE =25- 10=15 m BE= 15m

In ∆BCEBC= 14m, CE= 13m, BE= 15m

Semiperimeter (s)= (a+b+c)/2

Semiperimeter(s) =( 14+13+15)/2s= 42/2= 21ms= 21m

Area of ∆BCE= √ s(s-a)(s-b)(s-c)Area of ∆BCE=√ 21(21-14)(21-13)(21-15)

Area of ∆BCE= √ 21×7× 8×6

Area of ∆BCE= √ 7×3× 7× 4×2×2×3Area of ∆BCE=√7×7×3×3×2×2×4Area of ∆BCE= 7×3×2×2= 21× 4= 84m²

Area of ∆BCE= 84m²

Area of ∆BCE= 1/2 × base × altitudeArea of ∆BCE= 1/2 × BE ×CL

84= 1/2×15×CL

84×2= 15CL168= 15CLCL= 168/15CL= 56 /5m

Area of trapezium=1/2(25+10)(56/5)Area of trapezium= 1/2(35)(56/5)

10. The areas of a rectangle and a square are inthe ratio 3:2. If the length of the rectangle isdoubled and the side of the square is tripled,find the ratio of their new areas. 3

Answer»

We know that Area of rectangle = length * breadth

We know that Area of square = a^2.

Now,

Given that ratio of area of rectangle and area of square is 3:2.

= > (lb)/(a^2) = 3/2. ------ (1)

(i)

Given that length of rectangle is doubled = 2l.

Area = (2l)(b) = 2lb.

(ii)

Given that Side of square is tripled = 3a.

Area of square = (3a)^2 = 9a^2.

Now,

Ratio of areas:

= > (2lb)/9a^2

= > (2/9) * (lb/a^2)

= > (2/9) * (3/2) {From (i)}

= > 1/3

= > 1 : 3
