The thermometer Tina uses is calibrated in degrees Fahrenheit. Determine the temperature reading on her thermometer if the required constant temperature of 25 °C has to be maintained.

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.

hi,

the area of abcd is 245.

3*24=230

4*94=1039
