Question

Find the area of a reactangular plot whose one side is 8 m long and diagnol is of length 10 m

Answer 1

By Pythagoras theorem

Diagonal²=side²+II side²

10²-8²=II side²

100-64=II side²

36=II side²

6=II side

Area =hieght* base

Area =6*8

Area =48m²

Answer 2

I hope it will help you

Rectangle properties are,
Each angle is 90°

Therefore,

By Pythagoras thereon
h^2 = a^2 + b^2
10^2 = 8^2 + b^2
100-64 = b^2
36 = b^2
6m = b

Therefore,
Area of rectangle = l× b
6×8
48m^2
