5x^2 + 42x + 16

what would the area be if x = 5

The area would be 301 if x=5.

Step-by-step explanation:

Given expression is:

5x²+42x+16

We have to find the area when x=5

So putting x=5 in the given expression.

Area = 5(5)²+42(5)+16

Taking square of 5 and multiplying 42 by 5

Area = 5(25)+210+16

Area = 75+210+16

Adding all the terms

Area = 301

Hence,

The area would be 301 if x=5.
