Step-by-step explanation:
area = ( base 1 + base 2 ) ÷ 2 x height
50 = ( 10 + 15) ÷2 x height
50 ÷ 12.5 = height
height = 4
Hey there!
When two lines intersect, the pairs of angles that are directly across from each other (ex. the pair depicted in the image) are called opposite angles. These angles always measure the same.
This means that we can set the two expressions equal to each other and solve for x:
2x + 2 = 3x - 52
x = 54
Hope this helps!
Answer:
The percentage change is 140%
Step-by-step explanation:
Given
---- initial dimension
--- new width
--- new dimension
Required
The percentage increment
The length remains constant because only the width is extended.
The new area is:


Make L the subject

Substitute values for A and W


--- this is the length of the garden
Calculate the initial width:

Make W1 the subject



So, the initial area is:



The percentage change in area is:




Express as percentage
