A trapezoid is broken into 2 triangles and 1 rectangle. The triangles both have a base of 2 meters and a height of 5 meters. The

Lemur [1.5K]

Answer:

Part 1) The trapezoid has an area of $20\ m^2$

Part 2) The kite has an area of $21\ m^2$

Part 3) The area of the trapezoid is less than the area of the kite

Step-by-step explanation:

Part 1

Find the area of trapezoid

we know that

The area of trapezoid is equal to the area of two congruent triangles plus the area of a rectangle

so

$A=2[\frac{1}{2} (2)(5)]+(2)(5)$

$A=10+10=20\ m^2$

Part 2

Find the area of the kite

we know that

The area of the kite is equal to the area of two congruent triangles

so

$A=2[\frac{1}{2} (7)(3)]=21\ m^2$

Part 3

Compare the areas

The trapezoid has an area of $20\ m^2$

The kite has an area of $21\ m^2$

so

$20\ m^2< 21\ m^2$

therefore

The area of the trapezoid is less than the area of the kite

The perimeter of a rectangle is 52 feet. The length is 2 more than twice the width. What is the length of the rectangle?

SashulF [63]

Answer: The Length of the rectangle is 18 feet.

The width is 8 feet

Step-by-step explanation: Perimeter is 2w + 2L

Length here is <u>2w + 2</u> Substitute this value for L in the equation.

P = 2w + 2L

52 = 2w + 2(2w + 2) distribute and add

52 = 2w + 4w + 4

52 = 6w + 4 Subtract 4 from both sides, Then divide both sides by 6 to solve for w

48 = 6w

8 = w <u>The width is 8 ft</u>

Substitute into the original expression for Length

Length here is <u>2w + 2</u> : 2(8) + 2 16 + 2 = 18

<u>The Length is 18 feet.</u>

<u>Check:</u> in the original equation P = 2w + 2L

52 = 2(8) + 2(18)

52 = 16 + 36 TRUE!

The marked price of an article is Rs 400. If 5% discount is allowed, how much should

kow [346]

Answer:

Rs.380

Step-by-step explanation:

Given data

Price= Rs 400.

Discount= 5%

Let us find the amount of the discount

=5/100*400

=0.05*400

=Rs. 20

Hence the amount that should be paid for it is

=400-20

=Rs.380
