What is the base of a triangle with a height of 7.4 cm and an area of 48.1 cm2?

A. 355.94 cm
B. 6.5 cm
C. 13 cm
D. 177.97 cm

C. 13 cm

Step-by-step explanation:

A = 1/2bh        Use this equation to find the base of the triangle

48.1 = 1/2(b)(7.4)   Multiply

48.1 = 3.7b            Divide both sides by 3.7

13 = b

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
