Answer:

67.5 cm^2

Step-by-step explanation:

we know the length and width of the rectangle and the triangle in the compound shape.

The area of the rectangle is 10 times 5 = 50

the area of the triangle is

17-10 = 7

7 times 5 is 35

35/2 = 17.5

50 plus 17.5 = 67.5 cm^2

Answer: 67.5

Step-by-step explanation: Since this is a irregular shape, you have to split the two shapes. The rectangles area is 50, and the triangles is 17.5.

To find the area of a triangle multiply 1/2 × base × height

To find the area of a rectangle multiply base × height

Spencer borrowed $50 from his cousin, who charged him 6% simple interest each year. If Spencer pays his cousin back 3 years late

Orlov [11]

Given:

Principal = $50

Rate of simple interest = 6%

Time = 3 years

To find:

The amount after 3 years.

Solution:

Formula for simple interest:

$I=\dfrac{P\times r\times t}{100}$

Where, P is principal, r is the rate of interest in percentage and t is the number of years.

Putting $P=50,\ r=6,\ t=3$ in the above formula, we get

$I=\dfrac{50\times 6\times 3}{100}$

$I=\dfrac{900}{100}$

$I=9$

Formula for amount is:

$A=P+I$

Where, P is principal and I is the simple interest.

Putting $P=50,\ I=9$ , we get

$A=50+9$

$A=59$

Therefore, the correct option is B.
