1.	12. A rectangle measures 30cm by 25cmAA diagonal divides the rectangleinto two triangles findfind theof each triangles.area
Answer» Answer: 375 cm² Explanation: Method II: Rectangle is DIVIDED by diagonal AC in two triangles both of them will have equal area, so area of 1 triangle is, Area = 1/2 x b x h = 1/2 x 30 x 25 = 15 x 25 = 375 cm² Method II: or you can divide the area of rectangle by two, as diagonal divides rectangle into 2 equal Triangles, so area of rectangle is, Area = L x b = 25 x 30 = 750 area of triangle will be area of rectangle/2 = 750/2 = 375 cm²

Answer:

375 cm²

Explanation:

Method II:

Rectangle is DIVIDED by diagonal AC in two triangles both of them will have equal area,

so area of 1 triangle is,

Area = 1/2 x b x h

= 1/2 x 30 x 25

= 15 x 25

= 375 cm²

Method II:

or you can divide the area of rectangle by two, as diagonal divides rectangle into 2 equal Triangles,

so area of rectangle is,

Area = L x b = 25 x 30 = 750

area of triangle will be area of rectangle/2

= 750/2 = 375 cm²
