≈ 743 m²

Step-by-step explanation:

The figure is composed of a triangle and a semi- circle.

area of triangle = bh ( b is the base and h the height )

here b = 30 and h = 26, thus

A = × 30 × 26 = 15 × 26 = 390 m²

------------------------------------------------------

area of semi- circle = πr² ← r is the radius

Here diameter = 30, thus r = 30 ÷ 2 = 15, thus

A = 0.5 × 3.14 × 15² = 1.57 × 225 = 353.25 m²

Total area = 390 + 353.25 = 743.25 ≈ 743 m²

50.6

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
