The length of a rectangle is twice its width.

Mathematics

Furkat [3]3 years ago

The perimeter is the sum of all a shapes sides.

so if length is two times the width, you could write it as 2w.

2w + 2w + w + w = 42. Simplified, it's 6w = 42.
Divide both sides by 6, and you get w = 7.

Since the length is 2w, 2 * 7 = 14, so the length is 14

Area of rectangle is length * width, so do 14 * 7 which is 98. Slap on some units and your answer is 98 sq m

What is m∠2?<br> What is m∠1?
Greeley [361]

Answer:

<2 = 75

<1 = 105

Step-by-step explanation:

<2 and 75 are alternate interior angles and since the lines are parallel, they are equal

<2 = 75

<2 + <1 = 180    since the angles form a line

75+ <1 = 180

Subtract 75 from each side

<1 = 180-75

<1 = 105
