Find the area of the trapezoid. A drawing of a trapezoid with length of two parallel sides equal to a mixed fraction of one and

maxonik [38]

Answer:

$10cm^2$

Step-by-step explanation:

We are given that

Two parallel sides of trapezoid are

$a=1\frac{1}{2}cm=\frac{3}{2}=1.5cm$

$b=3\frac{1}{2}=3+0.5=3.5 cm$

Height of trapezoid, h=4 cm

We have to find the area of the trapezoid.

We know that

Area of trapezoid= $\frac{1}{2}(a+b)h$

Where a and b are two parallel sides

h=Height of trapezoid

Using the formula

Area of trapezoid= $\frac{1}{2}(1.5+3.5)\times 2$

Area of trapezoid= $10cm^2$

Hospital B (with 10 births a day), because with fewer births there will be less variability.

The two hospitals are equally likely to record such an event, because the probability of a boy does not depend on the number of births
