Two corresponding sides of two similar pentagons are 16 cm and 28 cm. what is the ratio of the areas of the two pentagons?

1 answer:

5 0

Answer: The ratios of the area would be 3.5 times larger.

If you compare the ratios of the sides, you will find that they increase by 1.75 times.

28 / 16 = 1.75

Now, lets write an equation to see what change that would make on the area, if the sides increase by 1.75.

LW = A

1.74L x 1.75W = 3.5A

We have to multiply the 1.75 by 1.75 to find the change in area, which is 3.5.

A rectangular turf of size 20 feet by 34 feet is surrounded by a flower bed of uniform width

BaLLatris [955]

Answer:

9.18 feet

Step-by-step explanation:

dimensions of whole area = (20 + x)(34 + x)

= 680 + 54x + x^2

where x is the width of the flower bed.

we know that x^2 + 54x + 680 = 1200

x^2 + 54x - 520 = 0

x = 9.18 or x = -63.18

width of flower bed cannot be negative therefore it is width 9.18 feet

As the triangles are similar corresponding sides are in the same ratio
So we have:_

24/6 = (30-2x) /x

4x = 30-2x
6x = 30
x = 5
