A triangle has the length of 6cm and height of 8cm. The area of the rectangle is 5 times the area of the triangle. The rectangle has the length of 12cm. Work out what the width is.

10cm

Step-by-step explanation:

Since the area of the rectangle is 5times the area of the triangle, let us first of all find the area of the triangle.

From the question, we obtained the following information:

h = 8cm

b =6cm

Area of triangle = 1/2 x b x h

Area of triangle = 1/2 x 6 x 8

Area of triangle = 24cm^2

But,

Are of the rectangle = 5times the area of triangle i.e

Area of rectangle = 5 x 24 = 120cm^2

Area of rectangle = L x w

L = 12cm

Area of rectangle = 120cm^2

W =?

120 = 12 x w

Divide both side by 12

W = 120 /12 = 10cm

24

answer:

some responsibilities that come with having a checking account -

1. we have to maintain check register with exactness to avoid checks being returned for insufficient funds which is called bouncing a check.

2. we need to update our check register each time we make a transaction using a convenience card. updating check register will   save   us from   overdrawing of checking account.

3. read the agreement the bank gave you when you signed up for our checking account. this includes all the fees and the minimum balance we need to keep in our account to avoid maintenance charges.
