Question

a garden consists of a sandpit surrounded by lawn. the sandpit is 4m x 2m and the garden is 15m x 3m. what is the lawn area?

Explanation:

Step1: Calculate garden area

The area of a rectangle is length times width. For the garden, length is 15m and width is 3m. So garden area is $15\times3 = 45$ square meters.

Step2: Calculate sandpit area

The sandpit is a rectangle with length 4m and width 2m. So sandpit area is $4\times2 = 8$ square meters.

Step3: Calculate lawn area

Lawn area is garden area minus sandpit area. So $45 - 8 = 37$ square meters.

Answer:

37 square meters
