Answer:
D. 95 + 47 + 5.12 12 ÷ 4 ≠ 4 ÷ 12.
Step-by-step explanation:
(70 +30) + 72 B. 21 + (-14) + (-53) O C. 67 +1 - 18. So 12÷4≠4÷1/4 + 3/4 + 2. C. 20 + 80 + (-11)
Answer:
129.5 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A =
h(a + b)
where h is the height and a, b the parallel bases
Here h = 7, a = 15 and b = 22 , thus
A =
× 7 × (15 + 22)
= 0.5 × 7 × 37
= 129.5
