Question

A sidewalk in front of Kathy’s house is in the shape of a rectangle four feet wide by 45 feet long. Find the perimeter and the area

Answer 1

Perimeter = 2(length + width)
Perimeter = 2(45 + 4)
Perimeter = 2(49)
Perimeter = 98 feet

Area = length x width
Area = 45 x 4
Area = 180 square feet

Answer 2

Parameter= 98ft

Area=180ft^2

Explanation:

Parameter= Length times 2 plus width times 2 or

L2+W2=P 4(2)+45(2)=8+90=98

Area= LxW=A^2

4x45=180^2
