Answer:
= 440 ft
Step-by-step explanation:
The perimeter of a rectangle is found by adding up all the sides. We use the formula
P =2(l+w)
where l is the length and w is the width
The length is 140 and the width is 80
P = 2(140+80)
= 2(220)
= 440 ft
From the figure, we can conclude that the little triangle is an isosceles triangle, the greatest angle is 90 because ∠A = 90 and they are supplementary, therefore, using the triangle sum theorem:
1 and 3 only answer is number 2
12.1 because 9 is greater than 5.
