A lawn is 10 m by 8 m. A 1 m path around the outside has area $40 m^{2}$ . If the path is made 2 m wide instead, what is its area?

Class 7Area of Paths and BordersPerimeter and Area

A $88 m^{2}$
B $160 m^{2}$
C $84 m^{2}$
D $80 m^{2}$

Step-by-Step Solution

New outer:

14 \times 12 = 168 m^{2}

. Path

= 168 - 80 = 88 m^{2}

. Doubling the width more than doubles the area, because the corners grow too.

Answer: A)

88 m^{2}
