The following shape is made by cutting an equilateral triangle from a rectangle. find its perimeter
length=7.2cm
width=13cm

Perimeter of triangle = 35.06 cm

Step-by-step explanation:

The missing side is Diagonal in the rectangle which is know hypotenuse.

so other two sides 7.2 cm and 13 cm and hypotenuse =?

according to Pythagoras theorem

c² = a² +b²      while c = hypotenuse

c² = 7.2² + 13 ²            c² = 51.84 + 169

c² = 220.84

c = 14.86          so hypotenuse is 14.86 cm

now for perimeter of a triangle

Perimeter of triangle = sum of all sides

                                 = a+ b +c

                                 = 7.2 +13 + 14.86

           Perimeter of triangle = 35.06 cm

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
