1 cm = 10 mm
? cm = 987 mm
987/10 = ? cm = 98.7 cm.
There are 98.7 cm in 987 mm.
I believe it's 7.5 but I could be wrong.
I think it would be 9, but the graph seems a bit unclear so I’m really sorry if that doesn’t help..
The area is equal to 230 CM.
area for rectangle :
area = width times length
area = 7 x 20 = 140CM
area for triangle:
area = 1/2 times base times height
area = 1/2 x 20 x 9 = 90CM
ADD:
140+90 = 230 CM
