The two parallel sides of a trapezium are 19.8 and 7.2 and its area is 135 cm²..find its height

Virty [35]

Answer:

10cm

Step-by-step explanation:

the formula for an area of a trapezium:

$\frac{(a + b) \times h}{2} = area$

where a and b are the parallel sides and h is the height. equating what we have:

$\frac{(19.8 + 7.2) \times h}{2} = 135$

simplify the numerator by adding 19.8 and 7.2=27

$\frac{27h}{2} = 135$

multiply both sides by 2

$27h = 270$

divide both sides by 27

$h = \frac{270}{27} = 10$

the height is 10cm

Spencer made a quilt for his cousin's doll. The quilt had a 7x7 array of different color square patches. If each patch is 1 3/4

Damm [24]

Answer:

$\frac{2401}{16}$ square inches

Step-by-step explanation:

Given:

The quilt made by Spencer had a 7×7 array of different color square patches such that each patch is $1\frac{3}{4}$ in long.

To find: the area of the whole quilt

Solution:

Side of each quilt = $7(\frac{3}{4})=7(\frac{7}{4})=\frac{49}{4}$

Quilt is in the form of a square such that area of square is given by $(side)^2$

Therefore, area of quilt = $(side)^2=(\frac{49}{4})^2 =\frac{2401}{16}$ square inches
