How do I find the perimeter and area of this triangle/:

Step-by-step explanation:

Given

base (BD)= 7 cm

Height (CE) = 4 cm

BC = 5.7 cm

CD = 5 cm

Now

Perimeter of the triangle

= BD + BC + CD

= 7 + 5.7 + 5

= 17.7 cm

Now

Area of the triangle

= 1/2 * base * height

= 1/2 * 7 * 4

= 14 cm²

Hope it will help :)❤

Perimeter: 17.7cm       Area: 4x7= 28cm²        I think

Step-by-step explanation:

perimeter: 5.7+5+7= 17.7 cm

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
