Question

Find the area of a rectangular field whose length = 12 m and diagonal = 13 m.​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

The area of a rectangular field is 60 square meter

Solution:

Given that,

Length = l = 12 m

Diagonal = d = 13 m

We have to find the area of rectangle

Find the width:

Let width = w

Then, by formula:

$w = \sqrt{d^2 - l^2}\\\\w = \sqrt{13^2 - 12^2}\\\\w = \sqrt{169-144}\\\\w = \sqrt{25}\\\\w = 5$

Thus width = 5 m

Find the area of a rectangular field:

$Area = length \times width\\\\Area = 12 \times 5\\\\Area = 60$

Thus area of a rectangular field is 60 square meter
