The area of a trapezoid is:

A=h(b1+b2)/2, in this case h=10, b1=8, and b2=16 so:

A=10(8+16)/2 cm^2

A=120 cm^2

A pineaple is 7 times heavy as an orange. The pineaple also weighs 870 grams more than the orange.

Lisa [10]

Answer:

1060 grams

Step-by-step explanation:

let the weight of the orange be x, then

pineapple weighs 7x, and also x + 870

equating the 2 expressions for the weight of the pineapple

7x = x + 870 ( subtract x from both sides )

6x = 870 ( divide both sides by 6 )

x = 145

The orange weighs 145 grams and the pineapple 145 + 870 = 1015 grams

Total weight of both = 145 + 1015 = 1060 grams
