The rectangular backboard of a basketball court needs to be assembled. its area is given as 18,900 cm2 and the width as 1.8 m. what is the backboard’s length in metres?

Step-by-step explanation:

Area of a rectangular figure is given by length times width

means

Area = length * width

we are given that the Area = 18,900 cm^2

width =1.8 m =1.8*100=180cm

using the formula and the given values we get

so simplifying the equation we get

length = 105 cm

length = 1.05 m

56

step-by-step explanation:

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
