Rectangle abcd is similar to rectangle wxyz . the area of abcd is 30 square inches. explain how to find the area, x , of wxyz

Area of rectangle WXYZ = ( Area of rectangle  ABCD ) /

Step-by-step explanation:

We know that two polygons are said to be similar if their sides are proportional.

As ABCD and WXYZ are similar,

Let this ratio be equal to k,

So,

Area of rectangle ABCD = 30 square inches = length × breadth = AB × BC = k WX × k XY = WX × XY = × Area of rectangle WXYZ.

So, if know value of k, we can find area of rectangle WXYZ

i.e, Area of rectangle WXYZ = ( Area of rectangle  ABCD ) /

step-by-step explanation:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
