Answer:
104cm^2
Step-by-step explanation:
Area of 1st rectangle
given
l=12cm
w=6cm
A =l×w
=12cm×6cm
=72cm^2
Area of 2nd rectangle
given
l=14-6=8cm
w=4cm
A=l×w
=8cm×4cm
=32cm^2
Total area =72cm^2+32cm^2=104cm^2
Answer:
Step-by-step explanation:
You do not need to where the formula comes from but, just for fun, here’s a hint
To add up the numbers 1 to 10
Write out the numbers
1 2 3 4 5 6 7 8 9 10
Write them backwards
10 9 8 7 6 5 4 3 2 1
Add up both lists
11 11 11 11 11 11 11 11 11 11
This is 10 × 11 = 110
But this is twice the sum as two lots were added together
So the sum of the numbers 1 to 10 is 110 ÷ 2 = 55
