Answer:
area = 49 ft²
Step-by-step explanation:
The area (A) of a triangle is calculated using the formula
A = bh ( b is the base length and h the height )
here b = 14 and h = 7
A = × 14 × 7 = 7 × 7 = 49 ft²
Answer:
The height of the second tree is 150ft.
Step-by-step explanation:
Well you have to set it up as a proportion, so
7 = 210
5 = x
Then you cross multiply, 7 times x is 7x, and 210 times 5 is 1050.
Now you have 7x = 1050
Then you divide 1050 and 7x by 7.
And the final answer is x = 150ft
Answer: The answer is 12 cm and 32 cm.
Step-by-step explanation: Let, 'x' cm be the breadth of the rectangle, then according to the question, the length will be (x + 20) cm.
Also, given that if the smaller side is made two times larger and the larger side three times larger, then the perimeter of the new rectangle would be 240 cm. So, we have
So, the width of the original rectangle is 12 cm and its length will be (12 + 20) cm = 32 cm.
Thus, the lengths of the sides of original rectangle are 12 cm and 32 cm.
