Answer:
420m^2
Step-by-step explanation:
by using Pythagorean theorem,we find breadth of rectangle
such that,

Step-by-step explanation:
Given :
Length of rectangle =35m
Diagonal of rectangle=37m
To find:
Area of rectangle
Solution :
A= l √ (d square -l square) sq. Units
Where
A is the area of rectangle
L is the length of the rectangle
D is the the diagonal of the rectangle.
Let us substitute the values in the above formula
A=35√(1369-1225)
A= 35√144
A=35*12 since √144=12
Area = 420 sq. m
Area of rectangle is 420 sq. m
Hope this helps u ✌
