On a scale drawing of scale 1: 50, the length and the width of a rectangle are 25cm and 16cm respectively. find the actual area of the rectangle in m2. need steps

100 m²

Step-by-step explanation:

The scale drawing has dimensions 25 cm and 16 cm

The actual rectangles dimensions are 50 times greater, that is

length = 25 × 50 = 1250 cm ← divide by 100 to convert to m

length = 1250 ÷ 100 = 12.5 m

width = 16 × 50 = 800 cm

width = 800 ÷ 100 = 8 m

Actual area = 12.5 × 8 = 100 m²

x/3-10=8

x/3=18

x=48

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
