Answer:
Trevor read 157.5 pages this week.
Step-by-step explanation:
Simple multiplication.
Multiply 5 by 5 first to get 25, carry the 2 on top and then multiply 3 by 5 to get 15, make sure to add 2 to get 17. The first line should be 175.
Put a 0 on the last digit to solve for the next digit. Multiply 4 by 5 to get 20, carry the 2 on top and then multiply 3 by 4 to get 12, make sure to add 2 to get 14. The second line should be 1400.
Add the numbers up to get 1575, since there is one number behind the decimal, you should put a decimal in front of the last 5 for the answer in which it is 157.5.

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
I am thinking it would be 6
