so the area is 120cm

A trapezoid

equation for area = h(a +b) ÷ 2

so you sub that in

6(9 + 5 ) ÷ 2 = 6 × 14 ÷ 2 = 42

So the answer is 42 inches

equation for area = p× q ÷ 2

so you sub that in

(3+3)×(4.5+6.5) ÷ 2 = 6×11÷2 = 3

So the answer is 33 cm

There are 128 students going on a field trip to pan for gold. If they are going in vans that hold 7 students each, how many vans

Viefleur [7K]

128/7 is roughly 18.3 so you would need 19 vans. 18 of them would fit all 7 so you’d have 126 so the last van would fit 2 students meaning it won’t be full
