This figure can be divided into two parts

1. A square of side 7 inches

2. A triangle of base 12 inches and height 7 inches

Lets calculate the individual areas and add them up

1. Area of the square = side × side

= 7×7 = 49 sq.inches

2. Area of the triangle = $\frac{1}{2}$ × base ×height

$\frac{1}{2}$ × 12 × 7

= 42 sq. inches

Lets add up the areas of the square and the triangle

= 49+42 = 91 in²

The length of each side of an equilateral triangle is increased by 20%, resulting in triangle ABC. If the length of each side of

kompoz [17]

Answer: Area of ΔABC is 2.25x the area of ΔDEF.

Step-by-step explanation: Because equilateral triangle has 3 equal sides, area is calculated as

$A=\frac{\sqrt{3} }{4} a^{2}$

with a as side of the triangle.

Triangle ABC is 20% bigger than the original, which means its side (a₁) measures, compared to the original:

a₁ = 1.2a

Then, its area is

$A_{1}=\frac{\sqrt{3} }{4}(1.2a)^{2}$

$A_{1}=\frac{\sqrt{3} }{4}1.44a^{2}$

Triangle DEF is 20% smaller than the original, which means its side is:

a₂ = 0.8a

So, area is

$A_{2}=\frac{\sqrt{3} }{4} (0.8a)^{2}$

$A_{2}=\frac{\sqrt{3} }{4} 0.64a^{2}$

Now, comparing areas:

$\frac{A_{1}}{A_{2}}= (\frac{\sqrt{3}.1.44a^{2} }{4})(\frac{4}{\sqrt{3}.0.64a^{2} } )$

$\frac{A_{1}}{A_{2}} =$ 2.25

The area of ΔABC is 2.25x greater than the area of ΔDEF.

Aniii geometry . solve the equation 4x-6=34

prohojiy [21]

(1) You can see that the 6 is being added to both sides.

You are trying to make both sides equal by adding 6, so it would be the Addition Property of Equality.

(2) 4 is being divided into both sides.

It would be the Division Property of Inequality. (you are dividing by 4 to make both sides equal)

"B" is the answer.

I hope this helps!
