Need help with working perimeter and area please

Mathematics
1 answer:
SVETLANKA909090 [29]3 years ago
5 0

Answer:

Area = 228 m²

Perimeter = 60 m

Step-by-step explanation:

The figure given shows a rectangle that has a cut triangular portion.

✔️Area of the figure = area of rectangle - area of the triangular cut portion

= L*W + ½*bh

Where,

L = 20 m

W = 12 m

b = 20 - (8 + 8) = 4 m

h = 6 m

Plug in the values

Area = 20*12 - ½*4*6

Area = 240 - 12

Area = 228 m²

✔️Perimeter = perimeter of rectangle - base of the triangular cut portion

= 2(L + W) - b

L = 20 m

W = 12 m

b = b = 20 - (8 + 8) = 4 m

Plug in the values

Perimeter = 2(20 + 12) - 4

= 2(32) - 4

= 64 - 4

Perimeter = 60 m

Divide the number 480 in a ratio of 3:5
Schach [20]

If it is a ratio of 3:5 you are dividing 480 into 8 parts (3+5).


So divide 480 by 8: 480/8 = 60


Then the ratio is (3x60):(5x60) or 180:300


To check it is correct, add up the two parts to see that they come to 480:


180+300 = 480. All good.


Hope this helps

never [62]
Your simplified answer is indeed 2/3 (or 60%, or 0.6) because the fraction 24/36 can be simplified by dividing both the numerator and denominator by 6, which leaves you with 2/3.
