Answer:
Original rectangle: Since the area of a rectangle is the length * width, the area of this rectangle is 7 * 2 = 14 square cm.
New rectangle: The new dimensions of this are 7*3 = 21 cm by 2*3 = 6 cm. To find the area, we multiply these two together. 21*6 = 126 square cm.
126 is 9 times greater than 14, so the area will be multiplied by 9.
Step-by-step explanation:
Angles in a triangle always add up to 180, so you could write an equation to solve for x:
31 + x + 4 + 3x + 9 = 180
44 + 4x = 180
- 44
4x = 136
÷ 4
x = 34
So now that you have the value of x, you can use substitution to find angles S and T.
34 + 4 = 38° = angle S
34 × 3 = 102
102 + 9 = 111° = angle T
I hope this helps!
