How does doubling the lengths of the sides of a rectangle to form a similar rectangle affect the area

MrRissso [65]

Doubling the lengths of the sides of a rectangle quadruple the area

<h3>How to determine the effect?</h3>

Let the dimension of the rectangle be L and W.

So, the area is

A = LW

When the lengths are doubled, we have:

A2 = 2L * 2W

This gives

A2 = 4LW

This means that the initial area is multiplied by 4

Hence, doubling the lengths of the sides of a rectangle quadruple the area

Mango farm contains 1250 mango trees. Each tree produces an average of 160 Mango’s during the summer how many such mango forms a

serious [3.7K]

If a farm contains 1250 trees, and each tree produces 160 mangoes, the farm produces

$1250 \times 160 = 200000$

This means that $k$ farms produce $200000k$ mangoes.

If you want 1 million mangoes, you must solve the equation

$200000k = 1000000 \implies k = \cfrac{1000000}{200000} = 5$

So, you need 5 farms.
