Question

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

Explanation:

Step1: Calculate total area

The total rectangle has length $5$m and height $6$m. Area of a rectangle is $A = l\times h$, so the total area $A_{total}=5\times6 = 30$ square - meters.

Step2: Calculate grass - area

The grass part is a rectangle with length $3$m and height $2$m. Using the area formula $A = l\times h$, the area of the grass part $A_{grass}=3\times2=6$ square - meters.

Step3: Calculate cement - area

Subtract the area of the grass part from the total area. $A_{cement}=A_{total}-A_{grass}$. So $A_{cement}=30 - 6=24$ square - meters.
