Hey mate ..

The formula of area of. trapezium is 1/2×(a+b)×h

where 'a' and 'b' are the "parallel sides" and 'h' is the height ..

So ..the answer is

1/2×(12.5+17.5)×6 =

1/2×30×60=

90cm^2

Answer:

90 cm²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h(b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = 6, b₁ = 17.5, b₂ = 12.5 , then

A = [tex]\frac{1}{2}[/tex] × 6 × (17.5 + 12.5) = 3 × 30 = 90 cm³
