Answer:

61.2 cm²

Step-by-step explanation:

The area (A) of a trapezoid is calculated using the formula

A = \frac{1}{2} h (b_{1} + b_{2} )

Substitute in given values

A = \frac{1}{2} × 4 × (13.8 + 16.8 ) = 2 × 30.6 = 61.2 cm²

Serenity picked 75% of the apples of a tree in her backyard. If she picked 30 apples, how many apples were on the tree to begin
Stells [14]

Given:

Serenity picked 75% of the apples of a tree in her backyard.

She picked 30 apples.

To find:

The number of apples on the tree in the beginning.

Solution:

Let x be the number of apples on the tree in the beginning.

Serenity picked 75% of the apples of a tree in her backyard.

Number of apples picked = 75% of x

                                           = \dfrac{75}{100}x

                                           = \dfrac{3}{4}x

She picked 30 apples.

\dfrac{3}{4}x=30

Multiply both sides by 4.

3x=4\times 30

3x=120

Divide both sides by 3.

x=\dfrac{120}{3}

x=40

Therefore, the number of apples on the tree in the beginning is 40.

(2+x)=11/5

(2+x)= 5.5

x= 5.5-2
