Question

Logan is putting hardwood floor in his kitchen and his bedroom. The kitchenmeasures 25 ft. by 25 ft. and the bedroom is 25 ft. by 20 ft. If Logan wishes topurchase a 20% excess of the hardwood, how many sq. ft. of hardwood does he need?

Answer 1

He needs 1 350 sq ft of hardwood

Explanation:

Data:

Kitchen's measurements: 25 ft by 25 ft

Bedroom's measurements: 25 ft by 20 ft

Excess wanting to purchase: 20% => 1.20

Formula:

Area of the kitchen: A(k) = side * side

Area of the bedroom: A(b) = side * side

Total Area: A = A(k) + A(b)

Amount of sq. ft of hardwood neede: T(h) = A + (A * 20%) = A + (A * 20 / 100) = A * 1.20

Solution:

A(k) = 25 * 25 = 625 sq. ft

A(b) = 25 * 20 = 500 sq. ft

A = 625 + 500 = 1 125 sq. ft

T(h) = 1 125 * 1.20 = 1 125 + ( 1 125 * 20 / 100 ) = 1 350 sq. ft
