Question

a rectangular area in a park is to be paved with decorative stone. the rectangle measures 3.5 m by 2.3 m
what is the area of the rectangle?

Explanation:

Step1: Recall the formula for the area of a rectangle

The formula for the area of a rectangle is \(A = l\times w\), where \(l\) is the length and \(w\) is the width.

Step2: Substitute the given values into the formula

Given \(l = 3.5\) m and \(w=2.3\) m. Then \(A=3.5\times2.3\).
Calculate \(3.5\times2.3=(3 + 0.5)\times2.3=3\times2.3+0.5\times2.3 = 6.9+1.15=8.05\)

Answer:

\(8.05\space m^{2}\)
