There is a right triangle shaped lawn in the school, and the length of its hypotenuse is 100 meters. Draw this lawn on the drawing, the two right angles are 3 cm and 4 cm, and the length of its hypotenuse is 5 cm How about the actual perimeter and area of this lawn

There is a right triangle shaped lawn in the school, and the length of its hypotenuse is 100 meters. Draw this lawn on the drawing, the two right angles are 3 cm and 4 cm, and the length of its hypotenuse is 5 cm How about the actual perimeter and area of this lawn

The actual one is in proportion to the one painted on the paper
It is 100m from the actual bevel and 5cm from the drawing,
Then the actual right angle side is 60m, 80m,
The girth is 100 + 60 + 80 = 240
1 / 2 area by 60 by 80 = 2400
