Question

grass and sand. find the area of the part with grass.
at right angles.)

Explanation:

Step1: Calculate the area of the large rectangle

The formula for the area of a rectangle is \(A = length\times width\). The length of the large rectangle is \(6\)m and the width is \(5\)m. So, \(A_{large}=6\times5 = 30\) square meters.

Step2: Calculate the area of the sand - part (small rectangle)

The length of the small rectangle (sand - part) is \(4\)m and the width is \(5 - 3=2\)m. Using the area formula \(A = length\times width\), we get \(A_{small}=4\times2=8\) square meters.

Step3: Calculate the area of the grass - part

Subtract the area of the small rectangle (sand) from the area of the large rectangle. \(A_{grass}=A_{large}-A_{small}\). So, \(A_{grass}=30 - 8=22\) square meters.

22
