Question

One side of rectangular field is 15 meter and one of its diagonals is 17 meter. Then find the area of the field.

Answer 1

Given,

One side of rectangular field = 15 meter

Length of its diagonal = 17 meter

To Find,

The area of the rectangular field.

Solution,

The formula for calculating the area of the rectangle is

Area of rectangle = length*breadth

First, we need to find the other side of the rectangle

By using Pythagoras' theorem

17² = 15²+x²

289-225 = x²

x = √64

x = 8 meter

Now,

Area = 15*8

         = 120 m²

Hence, the area of the rectangle is 120 m².
