Question

John’s Rectangle is _____ units long.

John’s Rectangle is _____ units wide.

The area of John’s rectangle is ____ units^2.

Answer 1

John's rectangle is 4 units long

John's rectangle is
`3(1)/(2)` units long

The area of John's rectangle is 14 units^2

Explanation:

A rectangle has four sides that comprise of two pairs of equal length sides

The side which is the longest side of a rectangle is known as the length, L, of the rectangle

The side which is the shortest side of a rectangle is known as the width, W of the rectangle

Based on the given measurement, the length of the given rectangle which is the length of longest side of the rectangle, which is the 4 units length side

Therefore;

∴ John's Rectangle is L = 4 units long

the width of the given rectangle which is the length of shortest side of the rectangle, which is the side with lengths 3 units and 1/2 units length side

∴ The length of the shortest side of the rectangle, W = 3 units + 1/2 units = 3 1/2 units

∴ John's rectangle is W =
`3(1)/(2)` units wide

The area of John's rectangle, A = L × W

∴ The area of John's rectangle, A = 4 units ×
`3(1)/(2)` units = 14 units².
