Find the area of the iscoseles triangle first answer=brainliest

Step-by-step explanation:

Perimeter of the isosceles triangle = 10+13+13

=> 36 cm

Semi Perimeter = 18 cm

Using Heron's formula to find the area:

=>

Where s is the semi perimeter and a,b and c are the sides

=> Area =

=> Area =

=> Area =

=> Area = 60 cm²

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
