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

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
Answer:-
The answer is 420 m²

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
