Let's figure this out by first finding the dimensions of the original rectangle, and then finding the dimensions of the new rectangle.
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.
Answer:
#2, AB is congruent to AD
Step-by-step explanation:
AB is congruent to AD.
since the bottom sides are corresponding, and the middle sides are corresponding, then if the outside sides are corresponding, then CAB is congruent to CAD
Answer:
Step-by-step explanation:
Given:
,
To find the value of y, let's find x by solving 3x = 15.
3x = 15
Divide both sides by 3
x = 15/3
x = 5
Plug in the value of x into
