16.8+8 to the 2nd power= 80.8
Answer:
height = 7 cm
Step-by-step explanation:
The area (A) of a trapezium is calculated using the formula
A =
h(a + b)
where h is the height and a, b the parallel bases
here a = 6, b = 12 and A = 63, hence
× h × (6 + 12) = 63
h × 18 = 63
9h = 63 ( divide both sides by 9 )
h = 7
Answer:
1.) four and six hundredths
4+.06
2) 5.2 5+.2
3. six and eighty nine hundredths
