7

a trapezoid

equation for area = h(a +b) ÷ 2

so you sub that in

8(9 +21) ÷ 2 = 8 × 30 ÷ 2 = 120

so the area is 120cm

8

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

9

A kite

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

sorry I can't see 10s measurements

What is 436/85 as a mixed number.?
ivann1987 [24]

Answer:

5  11/85

Step-by-step explanation:

First see how many times a whole number can be found.

436/85 = 5.1294

The denominator goes into the numerator 5 times.

Now we find a new numerator.

436 - (85 * 5) = 11 (this is the amount left over after we made 5 wholes.)

Now we see 5 11/85

It cannot be simplified further.
