High School

In △DEF, \( d = 64 \, \text{cm} \), \( e = 56 \, \text{cm} \), and \( f = 83 \, \text{cm} \). Find the area of △DEF to the nearest square centimeter.

Answer :

Answer:

√(64 + 56 + 83) = √203

√(-64 + 56 + 83) = √75

√(64 - 56 + 83) = √91

√(64 + 56 - 83) = √37

Area = (1/4)√203√75√91√37

= about 1,790 cm²
