Answer:
32 mm²
Step-by-step explanation:
perimeter of left rectangle = 2(9 mm + 3 mm) = 24 mm
length of right rectangle = L
perimeter of right rectangle = 2(L + 4 mm) = 2L + 8
perimeter of right rectangle = 24 mm
The perimeter of the right triangle is 2L + 8 and also 24, so 2L + 8 must equal 24. We can solve for L and find the length of the right rectangle.
2L + 8 = 24
2L = 16
L = 8
area of right triangle = length × width
area = 8 mm × 4 mm
area = 32 mm²
The ratio of time taken by Henry to time taken by Gavin is 3:5
Step-by-step explanation:
Time taken by Henry for each set = 36 minutes
Time taken by Gavin for each set = 1 hour
We will convert Gavin's time into minutes.
Time taken by Gavin for each set = 60 minutes
Ratio;
Time taken by Henry : Time taken by Gavin
Dividing by 6
Dividing by 2
The ratio of time taken by Henry to time taken by Gavin is 3:5
