Question

janes backyard has cement and grass. find the area of the part with cement. (sides meet at right angles.) square meters

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 \(6\) meters and the width is \(6\) meters. So the area \(A_1=6\times6 = 36\) square meters.

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

The length of the grass - part (small rectangle) is \(4\) meters and the width is \(2\) meters. Using the area formula \(A = length\times width\), we get \(A_2 = 4\times2=8\) square meters.

Step3: Calculate the area of the cement - part

The area of the cement - part \(A=A_1 - A_2\). Substitute \(A_1 = 36\) and \(A_2 = 8\) into the formula: \(A=36 - 8=28\) square meters.

Answer:

\(28\)
