Question

A triangle is 20 in tall and 5 in wide. If it is reduced to a width of I in then how tall will it be? ​

Answer 1

`\longmapsto \: h = (20)/( (5)/(1) )`

`\longmapsto \: h =4inches`

Answer 2

The new height is 4 inches

Explanation:

We need to divide the height and width by the same value.

The width is reduced by 5

5 inches to 1 inch is found by dividing by 5

5/5 = 1

We need to do the same to the height

20 inches / 5 = 4 inches

The new height is 4 inches
