Question

What is the person of the figure 7 cm 4 cm length times width

Answer 1

Given

l = 4 cm

w = 7 cm

Procedure

To find the perimeter of a rectangle, add the lengths of the rectangle's four sides.

`\begin{gathered} P=4+4+7+7 \\ P=8+14 \\ P=22\text{ cm} \end{gathered}`

The area of the rectangle is the region enclosed by the perimeter of the rectangle and is equal to product of length and width.

`\begin{gathered} A=l\cdot w \\ A=4\cdot7 \\ A=28cm^2 \end{gathered}`
