Answer:
A = 57.97 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A =
h (a + b)
where h is the perpendicular height and a, b the parallel bases
Here h = 6.2, a = 10.8 and b = 7.9, thus
A =
× 6.2 × (10.8 + 7.9) = 3.1 × 18.7 = 57.97 cm²
(8 times 4) - (2 times 3 = 8) divided by 2
Could you rewrite this please? It is fairly difficult to read.
A=pi(radius)^2
Radius=Diameter/2
Radius= 14/2=7yds
A=3.14(7)^2
A=153.86yds
