Question

12. A rectangle has a height of 1 and 3/4 feet. The
area is 5 and 5/6square feet. What is its length?

Answer 1

L = 3 1/3 feet

Explanation:

A = length × width

now let's change all the mixed numbers into improper fractions:

35/6 = 7/4 × L

we must divide each side by 7/4

35/6 ÷ 7/4 is the same as 35/6 × 4/7 = 20/6 or 3 1/3
