Question

what is the area of a kitchen floor that measures 15 1/4 ft by 13 and 3/4 ft

Answer 1

$\text {Area = Length x Width}$

Find Area
$\text {Area = } 15 \dfrac{1}{4} \times 13 \dfrac{3}{4}$

Change to improper fractions
$\text {Area = } \dfrac{61}{4} \times \dfrac{55}{4}$

Combine the fractions
$\text {Area = } \dfrac{3355}{16}$

Simplify
$\text {Area = } 209\dfrac{11}{16} \ ft^2$

Answer 2

15 1/4 ft. = 15.25 ft.
13 3/4 ft. = 13.75 ft.

Based on the given measurements, I concluded that the shape of the kitchen is rectangle.
A = L x W
A = 15.25 ft. x 13.75 ft.
A = 209.6875 ft.
