Convert that decimal into a reduce fraction

4710. we have 1 number after the decimal point so

multiply both numbers by 10. so 4.71= (4.7x10)(1×10)=4710.

the 4th choice is the correct one

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
