Question

find the aera of rectangular plot if one side is 35 metre and diagonal is 37 metre

Answer 1

$\large \tt AHOY!! \:$

given :-

one side of the rectangle = 35m

diagonal of the rectangle = 37m

formula for finding the area of a rectangle is l × b.

so first we have to find the length of another side.

let the other side be x.

by using Pythagoras theorem,

=> 37²(hypotenuse) = 35²(length) + x²(breadth)

=> 1369 = 1225 + x²

=> 1369 - 1225 = x²

=> 144 = x²

=> x = √144

=> x = 12

hence, the length of the other side is 12m.

therefore it's area = l × b

= 35 × 12

= 420m²

Answer 2

Q) Find the area of a rectangular plot,one side of which measures 35m and the diagonal is 37 m.

Answer:-

The answer is 420 m²

Explanation-

the b = 35 m and diagonal= 37 m which also

gives us two right angled triangle. We know

that

(b)² + (l)² gives us the square of the

hypotenuse.

So, we will reverse it means (h)²- (b)² = (l)²

So, (37)² - (35)² = 1369 - 1225 = 144 which is

the square of 12.

Length = 12

Breadth = 35

Area = 12×35= 420 m²
