Question

find the area of a rectangular plot one side of which measures 35 cm and the diagonal is 37 CM

Answer 1

Let ABCD is a rectangular plot , in which BC = 37 cm and CD = 35 cm.



Therefore,



( BC )² = ( CD)² + ( BD)²



( 37)² = (35)² + ( BD)²





( BD)² = (37)² - (35)²



( BD)² = 1369 - 1225



( BD)² = 144


BD = √144 = 12 cm.



Therefore,


Area of rectangular plot = 12 × 35 = 420 cm².

Answer 2

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

Answer:-

The answer is 420 cm²

Explanation-

the b = 35 cm and diagonal= 37 cm 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 cm²
