W = width
3w + 7 = length
Equation: 3w + 7 + w = 75
Combine like terms: 4w + 7 = 75
Subtract 7 to the other side: 4w = 68
Divide both sides by 4: w = 17
Width = 17
Length = 3(17) + 7, so 58
Answer:when in doubt go with c
Step-by-step explanation:
just do it
Surface Area= Length × hypotenuse+ length × width+2(1/2 base × height)+Lenght×base
Surface Area= 19×25+19×7+24×7+19×24
SA=1232 m²
