The similarity ratio of two similar polygons is 7: 4. find the ratio of their areas

The ratio of their areas 49:16

Step-by-step explanation:

The similarity ratio is 7:4. Therefore, the scale factor is k = 7/4

The scale factor of the area k^2 = 7^2/4^2

= 49/16

Hence, the ratio of their areas 49:16

Hope this will helpful.

Thank you.

a triangular prism is a 3 dimensional shape composed of triangles and rectangles. it is made from two triangular bases and three rectangular sides.  

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.
