Answer:
3/4 of a foot will cost $2.25.
Step-by-step explanation:
This question is solved by rule of three, due to proportions.
One foot of lace costs 3 dollars. How much is 3/4 of a foot going to cost?
1 foot - 3 dollars
3/4 foot - x dollars
![x = 3 \times \frac{3}{4} = \frac{9}{4} = 2.25](https://tex.z-dn.net/?f=x%20%3D%203%20%5Ctimes%20%5Cfrac%7B3%7D%7B4%7D%20%3D%20%5Cfrac%7B9%7D%7B4%7D%20%3D%202.25)
So
3/4 of a foot will cost $2.25.
7.8 is a rational number, sqrt(60.85) is irrational
The equation given in the question has one unknown variable in the ofrm of "x" and there is also a single equation. So it can be definitely pointed out that the exact value of the unknown variable "x" can be easily determined. Now let us focus on the equation given in the question.
x/35 = 7
x = 35 * 7
x = 245
So we can find from the above deduction that the value of the unknown variable "x" is 245. The correct option among all the options given in the question is option "B". I hope the procedure is not complicated for you to clearly understand.

Answer:
The first shape is triangle; area of a triangle = 1/2*b*h
= 1/2*7*3
= 1/2*21
= 21/2
= 10.5
The second shape is rectangle; area of rectangle = l*b
= 7*3
= 21
Total area:
10.5+21
= 31.5
