georgette used 21m2 of wrapping paper to wrap20 boxes of presents.3/5 of the boxes were small and the rest of the boxes were large. each large box required twice as much wrapping paper as each small one . how much wrapping paper was needed for 1 large box?

Answer 1

large boxes=3
small boxes = 2

small⇒ X m²
large⇒ 2X m²

3 * 2X + 2 * X =21
6X+2X=21
8X=21
X= 21/8
    =2.625

1 large box needs = 2*2.625
                              =5.25 m² wrapping paper
